we have that
Find the equation of a line perpendicular to y - 3x = – 8 that passes through the point (3, 2)
y - 3x = – 8-----> y=3x-8------> the slope m=3

Based on the link I shared above, the value of [tex]\arctan(-\sqrt3)[/tex] is that number [tex]x[/tex] that satisfies

[tex]\tan x=-\sqrt3[/tex]

where [tex]x[/tex] lies in what you might call the "principal branch". That is, [tex]\arctan x[/tex] is bounded below by [tex]-\dfrac\pi2[/tex] and above by [tex]\dfrac\pi2[/tex], so it's only a valid inverse of [tex]\tan x[/tex] if we restrict the domain of [tex]\tan x[/tex] to [tex]-\dfrac\pi2<x<\dfrac\pi2[/tex].

In other words, [tex]x[/tex] is some angle whose terminus lies in either the first or fourth quadrant (I'm assuming you're at least a little familiar with the typical unit circle diagrams used in trig). The only value of [tex]x[/tex] in this domain that satisfies the equation above is [tex]x=-\dfrac\pi3[/tex].

On the other hand, [tex]\mathrm{Arctan}(-\sqrt 3)[/tex] captures all possible values of [tex]x[/tex] that satisfy

[tex]\tan x=-\sqrt3[/tex]

First, we know that [tex]\tan(x+\pi)=\tan x[/tex] (in other words, [tex]\tan[/tex] has a period of [tex]\pi[/tex]), so in fact [tex]\tan(x+2\pi)=\tan(x-2\pi)=\cdots=\tan x[/tex] as well. In general, then, we know that [tex]x+n\pi[/tex] will be a valid solution to the equation above, where [tex]n[/tex] is any integer.

Earlier we found that [tex]\arctan(-\sqrt3)=-\dfrac\pi3[/tex], so in this case, [tex]\mathrm{Arctan}(-\sqrt3)=-\dfrac\pi3+n\pi[/tex] for [tex]n\in\mathbb Z[/tex].

A. The expression "arctan(-√3)" represents the inverse tangent function of the value -√3. The inverse tangent function returns an angle whose tangent is equal to the given value.

To evaluate arctan(-√3), we can use a calculator or reference table that provides trigonometric function values. In this case, the value is approximately -60 degrees or -π/3 radians.

A 3-lb force acting in the direction of the vector (3,-1) moves an object just over 9 ft from point (0,5) to (6,-2). Find the work done to move the object to the nearest foot-pound

Answers

Answer: The Work done to move the object is  [tex]=23.15 \text { foot pounds }[/tex]

Step-by-step explanation:

Given;

Force F=3 [tex]l b s[/tex]

Vectors of F= (3,-1)

Moves object to a distance=9 [tex]f t s[/tex]

Let A and B be the displacements Vectors

A= (0,-5)

B= (6,-2)

To Find:

Work done in foot-pounds

Solution:

Work done [tex]W=F \times D[/tex]

Direction of force vector= (3,-1)  (i, j)  

                                        =3i-j

Unit of force vector [tex]=\sqrt{3^{2}+\left(-1^{2}\right)}[/tex]

                                 [tex]=\sqrt{9+1}[/tex]

Force vector=(Force/Unit Vector)Direction of  force vectors

                   F=[tex]3 / \sqrt{10} \times(3 i-j)[/tex]

Direction of motion vector= (B-A)  

                                          = (6,-2)-(0,-5) x i,j)

                                          =(6-0),(-2-5) x (i, j)

                                          =(6,-7) x (i, j)

                                          =6i-7j

Unit of motion vector [tex]=\sqrt{6^{2}+\left(-7^{2}\right)}[/tex]

                                   [tex]=\sqrt{36+49}[/tex]

                                   [tex]=\sqrt{85}[/tex]

Motion Vector= (Distance moved by the object/Unit motion vector) × (Direction of motion vectors)

                        [tex]D=9 / \sqrt{85} \times(6 i-7 j)[/tex]

Workdone [tex]W=F \times D[/tex]

                  [tex]= [3/ \sqrt{10} \times (3i-j)] \times [9/ \sqrt{85} \times (6i-7j)][/tex]

                  [tex]= [3/ \sqrt{10} \times 9/ \sqrt{85}] \times [(3i-j)  \times(6i-7j)][/tex]

                  [tex]= [3/3.1623 \times 9/9.2195] \times [(3\times6) + ((-1) \times (-7))][/tex]

                  [tex]= [0.94867 \times 0.97619] \times [18+7][/tex]

                  [tex]=23.15 \text { foot pounds }[/tex]

Result:

   Work done to move an object [tex]=23.15 \text { foot pounds }[/tex]

Answer:

[tex]W = 25.617\,lbf\cdot ft[/tex]

Step-by-step explanation:

The work done to move the object is:

[tex]W = F \cdot s \cdot \cos \alpha[/tex]

The angle of the force with respect to change in the position vector is:

[tex]\alpha = \tan^{-1}\left(-\frac{7}{6} \right) - \tan^{-1}\left(-\frac{1}{3} \right)[/tex]

[tex]\alpha \approx 18.415^{\textdegree}[/tex]

The magnitude of the work done is:

[tex]W = (3\,lbf)\cdot (9\,ft)\cdot \cos 18.415^{\textdegree}[/tex]

[tex]W = 25.617\,lbf\cdot ft[/tex]

At a high school 7 student volunteer for a committtee how many different 5 person committees can be chosen

Answers

Total number of volunteer students for a committee = 7
Number of committee = 5

Number of ways of selecting the committee from the 7 volunteers = 7C5 = 7!/(5!*2!) = 21 ways.

There are 21 ways in which the 5-committee member can be selected from the 7 volunteers.

Using the combination formula, 21 different 5-person committees can be chosen from a group of 7 students.

To determine how many different 5-person committees can be chosen from a group of 7 students, we use the concept of combinations, specifically the combination formula which is defined as:

C(n, k) = n! / [k! * (n - k)!]

where n is the total number of items to choose from, k is the number of items to choose, and the exclamation point represents a factorial, which is the product of all positive integers up to that number.

Applying this to the given problem, we have:

C(7, 5) = 7! / [5! * (7 - 5)!]

This simplifies to:

C(7, 5) = (7 * 6) / (2 * 1)

Therefore, C(7, 5) = 21.

There are 21 different 5-person committees that can be formed from 7 students.

He altitude of a triangle is increasing at a rate of 3000 centimeters/minute while the area of the triangle is increasing at a rate of 3500 square centimeters/minute. at what rate is the base of the triangle changing when the altitude is 10000 centimeters and the area is 89000 square centimeters?

Answers

By definition, the area of a triangle is given by:
 A = (1/2) * (b) * (h)
 Where,
 b: base of the triangle
 h: height of the triangle
 Deriving the area we have:
 A '= (1/2) * ((b') * (h) + (b) * (h '))
 Clearing b' we have:
 b '= (2A' - (b) * (h ')) / (h)
 We must look for the value of the base:
 A = (1/2) * (b) * (h)
 Substituting values:
 89000 = (1/2) * (b) * (10000)
 b = (89000) / (5000)
 b = 17.8 cm
 Then, the speed at which the base changes is:
 b '= (2 * (3500) - (17.8) * (3000)) / (10000)
 b '= -4.64 cm / min
 Answer:

Explain how you would find 90% of 120.

Answers

Our trick here is to think that a fraction in %

land is the same as the correspondent in "number" land; so we can write:
100%
90%
= 120x
Where X is the correspondent of 90% in numbers.
Rearranging: x = 120⋅
90% 100% =108
If 120 = 100% then how much of it is 90%?

To find out you will have to multiply 90 with 120 and then divide what you get with 100.

90 x 120 = 10800

10800/100 = 108

so 90% of 120 is 108.

The length of a rectangle is 5 yd less than three times the width, and the area of the rectangle is 28 yd2 . find the dimensions of the rectangle.

Answers

The answer is 4.

The formula for the area of a rectangle is A = lw. Substitute, so then it's 28 = (3x-5) * x, and you evaluate.

Hope this helps you! And rate so I can see if I did well!

The dimensions of the rectangle are width = 4 yds and length = 7 yds.

What is the area of the rectangle?

The area of a rectangle is defined as the product of the length and width.

The area of a rectangle = L × W

Where W is the width of the rectangle  and L is the length of the rectangle

We have been given that the length of a rectangle is 5 yds less than three times the width,

The area of the rectangle is 28 yds square.

Let the width of the rectangle is x

So the length of the rectangle = 3x - 5

The area of a rectangle = x × (3x - 5)

28 = 3x² - 5x

3x² - 5x - 28 = 0

(3x + 7)(x - 4) = 0

3x + 7 = 0 and and x - 4 = 0

x = -7/3 and x = 4

Take x = 4 as the width

So the length of the rectangle = 3(4) - 5 = 12 - 5 = 7

Therefore, the dimensions of the rectangle are width = 4 yds and length = 7 yds.

The students put a few drops of iodine on each white powder. One powder turned black; they guessed that it was cornstarch. They heated the powders in a Bunsen burner flame to see if any would melt. One did and they guessed it might be a sugar. Which test result indicated a chemical change had taken place? A)dissolves in water B)feels slippery in water C)melts when heated in a flame D)turns black when iodine is added A key goal of the Chicano Movement was to: Maggie ebought 52 ounces of swordfish selling for $6.92 per pund.
